Block Trade
A large privately negotiated securities transaction, typically 10,000+ shares or $200,000+, executed outside the public exchange.
Explained Simply
Block trades are large orders that institutions execute off-exchange to avoid moving the market. They're reported after execution and can signal institutional conviction. A block buy at or above the ask price (a "buyer-initiated" block) is bullish — it means someone was willing to pay up for immediate execution. Block trades are often routed through dark pools or negotiated directly between institutions via a block desk.
How Tradewink Uses Block Trade
Block trade prints are captured by our dark pool scanning loop. The AI analyzes block trade direction (buyer vs. seller initiated), size relative to average daily volume, and price relative to VWAP. Multiple buyer-initiated blocks in the same stock within a short window strongly suggest institutional accumulation and boost signal confidence.
